To alll whom it may concern.'4 l

Be it known that L CHARLES A. JUENosT, a citizen of the United States, and a resident of Croton Falls, lin the county of -West.-

chester and State of New York, have invented. certain new and useful Improvements in Delivery Mechanism, of which the following is a specification.

This invention' relates to book covering machines and in particular to the delivery' vided with bookf clamps is em'ployed to' carry the books in a vertical position with their backs lowermost consecutively from one operating device nto another in order to have performed thereon the successive steps necessary in binding or applying a cover to a book. -Book binding machines o this general type are shown inthe copending ap plication Serial No. 791,942, filed Sept. 26, 1913, and in Patent No. 1,193,395, August l, 1916. When the book carrying conveyers in such machines have carried the books in sucgession past the various operating devices, they thenv convey the covered books to a point -in the path of tra'vel of the conveyer where the clamps are opened andthe books discharged into the delivery apparatus. A delivery apparatus that has been largely employed or'conve ing the books away from the .point of discharge ofV the conveyer clamps, consists ofen endless conveyer provided with upwardly projecting' blades arranged to hold the books while they are being carried by the delivery mechanism in the same vertical position in which they were received from the machine conveyer.

. The direction of travel of the delivery conveyer 1s ordinarily away from the machine, thus adding materially to .the amount of floor Vspace occupied by the machine. The consequent tendency to restrict the length of the delivery conveyer as much as possible combined with the ever-present tendency to increase production by increasing the speed of operation has given rise to the objection that the covered bookswere not .allowed sufficient time for the adhesive material used -in applying the covers to firiA ly set before the books had arrived at the/v eliver end of the delivery conveyer. The main o jects of this invention are to provide a delivery apparatus which will convey the linished books through a substantialdistance inwhich the adhesive material used in applying the, books will have time to dry, and to reducethe ad-` ditional floor space occupied by the delivery apparatus to a minimum.

With these objects in view the invention consists principally in providing a book covering machinehaving .a book conveyer-arranged to support and carryvbooks while operations are being'performed thereon, with a delivery conveyer adapted to receive books from the main book conveyer and to carry them for a substantial distance longitudinally of the machine.

In the accompanying drawings there is illustrated a `preferred embodiment of the, inventlon, but it is to be understood that the invention may be carried out by other enibodlments and by mechanism widely different from that selected for illustration.`

Figures 1 and 2 together show the entire j plan view of the'machine., and instrumen' talities which act upon the books being omitted for the sake of clcarness. These instrumentalities may be of the character shown for instance in Patent No. 1,193,395.

Figs. 3 and 4 together constitute a complete side elevation of the machine.4 with parts omitted as in Figs. l and 2. 'i

F ig. 5 is an enlarged lan viewrwitliparts removed for the sake o clearness and showing the operatin parts at the end of the ma chine shown in ig. 1.

Fig. 6 is a vertical section taken along the line 6 6 in Fig. 5 and showing a conveyer clamp and its manner of coperation with the. conveyerguide where the direction of travel is beingchanged.

In the particular embodiment of the -invention disclosed there is shown a book'covering Inachine of the general type inwhichl a horizontally traveling conveyer carries the books successively in avertical position with their backs lowermost froml one operating mechanism to another, and finally deposits the covered book at the delivery ap aratus. A preferredmethod for causing the ooks to be held by the traveling conveyer of the ma'- chine is by means of clamps which may be opened to release the books by means of a cam mounted on the frame-work of the me;-v

The delivinstance is of the belt type on which the books are conveyed in a horizontal position and a rotatable transferring device 1s preferably made use of for transferring the books as they are released by the clamp to the receivin end of the delivery conveyer just beneat The delivery conveyer is preferably mounted Within the boundaries ofthe framework of the machine and is arranged to convey the books from one end of the machine to the other.

In this particular instance a bookcoverin?,r machine, the framework of which is indicated generally at 1, is provided with a book eonveyer 2 made up of the clan'ips 3 which are hinged together to form the links of the conveyor. For the sake of clearness only a few of the links of the book conveyor are shown. The clamps 3 are preferably made up of the back nieuibers ($5 and the hinged member and for the sake of clearness a number of the clamps are represented on the drawing merely by the back members 65. For a like reason a complete conveyor is not shown audit is to be. understood that the book eonveyer 2 is made up of links 3 which are joined together to torni an cndless chain extendingr the whole distance about the perimeter of the machine. The conveyeri is arranged to'travelabouttheperimeter of the machine which is preferably of' substantial length so that. long stretches 66 ahdp? are provided in which the books travel i'n right-line, paths on opposite sides of the machine. Unc or both of these stretches may have mechanisms arranged tberealong' adapted to perform operations on the books, but preferably the stretch (36 which receives` the books at the lett hand end thereof is 'used ilior this purpose, while the seeoi'id stretch G7 is lett colnparat-ively or entirely- .free o't' operating' nicchanisn'i so that the book covers will be given an oppor tnnity to set to some extent beton` the' arc transl'crred to the delivery ronvever. For the reasons just given the two right-line stretches (i6 and (i7 will be generally referred. to the receiving stretch and the setting stretch, respectively.

iso

ards 7 and 8 mounted The del'ivery conveyor 4 preferably of the belt typev and is mounted to turn about the rollers 5 and (i, the horizontal shafts of which are supported in the. vertical .standat opposite ends of the machine. The course of the belt Conveyer is preferably directly through the framework of the n'iachine, below and generally parallel to the long receivingand setting" stretches GG and G7 ot the main con- Ve'yer'2.

The receivlng end ot the delivery conveyor 4 is preferably .supported some di.s tafnce below the 'deliveryend oi' the main conveyor 2 in order to pro de room iu which 'to mountua device 9 forlztransterring,the

books from the clamps as they are released and depositing them on the delivery belt. The device 9 consists of a rotatable transferring member of the general S- shaped type in which the peripherally arranged distributors l0 form pockets with the arc-shaped distributor supporting members l1. The transferring i'levice 9 is arranged. to rotate at such a speed that the pockets are successively brought to position to receive the books coincidentally with the arrival ot the clamps` at book releasingv position,

The transforring device 5) is preferably arranged to rotate about a horizontal axis 12 which is mounted transversely to the di rection of travel of the belt. conveyer `1l.. At the end ot the book coveringr machine where the books` are transferred to the-delivery apparatus, the course of the book conveyer is preferably at right angles to the direction of travel ot 4the delivery conveyer, and this particular portion 68 ot the conveyor path will be referred to as the delivers` stretch ot the conveyor. "lhc object of providing' a right line deliver).v stretch at right angles to the direction oi" travel ot the delivery convelver l. is to drposit the books in swbstantiai zrlincm. and transverse thc direction of travel ot the delivery conveyer. the books 70 are received trom the clamps 3 in which they are carried with their backs lowern'iost and are deposited by the transferring device on the conveyor belt in a flat position transverse the belt with their barks overlapping` and arranged to trai-cl foremost in their .new direction of travel.

In order to provide space for a suiiicient travel of the main conveyor at right angie#- across the end of the machine where the books 'are released, the .settingy stretch ff? of the conveyor track 'i3 is mounted at angle to the longitudinal axis ol1 the ma chine .so that the reci-ivingr and the sett stretches diverge from each other and much farther apart. at the releasing and than at the opposite end of tire machine, as plainly shown in Figs. l and 2. of the drawinv. The couveyer track prefers-bl ,formed of the. U--shaped channel mernb 14 spaced apart vertically and the channels of which face each other to provide runways for the rollers 15 carried by the book clamps 3. The channel members 14 are preferably cut awa-y Where the transverse delivery stretch G8 at the end of the. ina-- chine curves away into the long' stretches at the .sides of the machine to avoid locking the clamp rollers 15 in the curved channelsy and stopping the progress of' the ('r-onveycr.

'At these, curves the vertical bearer rolls i6 lt will thus be seen that. j

. ries; a gear @lil which nufsl'u It'fhas been found desirable to provide means supplement-.i1 to the transferringg,r device 9 for securing an orderly ar angement of the books on the delivery conveyor belt 4. This means takes the form of the jogging members 18 mounted on the arms 19 in turn secured to the .rook shafts 20. A, rod 21 al;- taohed to an upwardly extending` arm 22 on one shaft and to a corresponding downwardly extending arm 22 on the other serves to rook the 'shafts 20 in unison.

l A drive shaft longitudinallysupported in the fran'iework of the machine serves to convey poner to the'ope 'atinglr parte thereof. Any suitable means may be employed for conveying motion to the drive shaft 23 from a lsource external to the machine. l'le conveyor 2 4is preferably driven by the sprocket Wheel 2li shown at thi: aand end oil the machine. The sprocket wheel 9A is provided with notehes 25 in which ythe rollers 15 on the Clamping members 3 are adapted to engage. The sprocket whe' "ll-l iis mounted on a nei-tical shai't Whit` na secured to it a bevel gear 27. Mounted on the end of the drive shaft 23 a l' ive] pinion 28 which is adapted to mesh with thegear 27 and thereby drive the wheel 2l. and the eonveyer 2.

In order to drive the delivery conveyor Il, a gear 29 is secured to the drive shaft 23. This gear Q9 meshes with al corresponding gen1-B0 mounted on a stub shaft 31 journaled in. a suitable 'bracket The stub shaft 3l is else provided at :its end with a bevel gear 33 which meshes with :i corresponding gear 3ft mounted on. a counter sanft 35 andy provided at its opposite end with a sproeket 36. A set-.ond sprocket 39 carried by the eounter shaft 37 serves to drive a sprocket 'lll n'iounted on ashait 4l which is Journaled in the supporting-standard 8 at the end olfthe delivery eonvr \rr. A suitable syn'oeket chain 42 conveys motion from the sprocket 39 to the sproeliiet l0;

The shaft 11:1` carries a pinion Li3 which.,

meshes with :mother pinion 414 carried. bv' the shaft 4115 of. the delivery belt drive roller tf. It will. thus be seen that the rotation ol' the drive shaft 23 is utilized through the chain of mechanism just deseribed 'to drive 'the delivery belt oonveyer as woll as the nuria book oonveyia" The transferring; device 9 also driven om the main drive shall. 23 hy means of the bevel. gear @lo mounted on the drive Sha/ft and meshing with a. .:orresjionding bevel gear elf! mounted en a, count-e. .'leliailft 48 which is sI-iitabl).Y traine-- Work: of the machine. lhe sha spending' 5i.) in The shaft 51. carries i `serves to drive the tra .throng the epi-reitet i sprocket Wheel 55, the latter mourned on the shaft 12 of the transferring device.

A cam 5G mounted on the drive shaft 23 engages a eem roller 57 carried by an arni 58 which is secured in turn to one ofV the rook shafts 20 to thereby operate the jogging members 18 which have been already re ferred to. Y

Because of the great length olf the con veyer belt IL it has been found desirable to support it at intervals intermediate its ends. For this purpose inuiiportinfgr rods 59 have been provided which are mounted to be verF tieally adjusted on the supporting standards G0, one pair of which forms a. support l'or one end 0f the rook shafts 20. Suitable clamping;1 nielnbersll are provided by means of which the cross rods 5D can be secured at any desired elevation.

In the operation of the machine, lhr hooks are placed in position within the clamps 3 while they are being held open by the action of the cani 6:2 on the roller (il-l, The oools are then carried aloiig the lirst or receiving stretch GG ol the nnu-:hine where they are .successively operated upon by `the va.- rious nueehanisins provided :lor the purpose. lVhen the books ha ve been carried .past the operating device they are then Corti yyed along; the settii stri-itch (37 at the opposite side of 4*he machine during whieli time the adhesive material mnployed in aifplying the Covers to the books will havevan opportunitv to set to soule extent. When the books have been conveyed tlnfiugh the setting streteh 6'! they are then carried into the transverse delivery stretch (it :it the 11i-leasing' end o'l' tho machine whore the olainps are engaged by the oam G2 and the hooks thereby released.
